Next, I installed the downloaded version of your app via App Loader. Apparently, the install was successful. When I launched your app, the message "Uncaught exception: java.lang.NullPointerException" popped up in a dialog window. I tried launching again. Again, I got the exception.

When I tried to delete your app from the App Management screen, my phone hung up. I successfully deleted your app by using BlackBerry Master Control Program.
